Panasonic HVX 200 users, a little help please?

A few questions for anyone using a panasonic HVX 200. Any help would be greatly appreciated.
Firstly what settings are you using? I have mine set in 1080i/24p but underneath that in the recording setup, it has 480i rec mode & that is set in DVCPRO50, but it is in blue & not green like the other settings.
I can't change that at all. I assume i want to record in DVCPRO100/HD
Is there a reason why i can't change the setting?

Also does that mean i am recording in 480i & not 1080i?
I am recording to P2 card, i just bought a new 64gb card.

Also i have two 5400mah batteries that show about 70mins of usage after a full charge, does that sound right? I would have thought they would last a little longer. Maybe time for some new batteries?

What program are you using to view the footage on your computer? I use windows 7.

Thanks in advance for any help with these.
Cheers Pete.
